ELT3052M-V

Triac, SCR Output Optoisolators Overview

The ELT3052M-V is a triac output optocoupler manufactured by Everlight Electronics Co Ltd. It consists of a gallium arsenide infrared emitting diode optically coupled to a monolithic silicon random phase photo triac. The device provides an isolation voltage of 5000 Vrms between input and output. Key electrical parameters include a peak breakdown voltage of 600 V, a minimum static dV/dt of 1 kV/µs, and a maximum LED trigger current (Ift) of 10 mA. It is housed in a compact dual-in-line package.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'M' against the manufacturer's official documentation to confirm pinout configuration and packaging type. Ensure compliance requirements such as UL, VDE, or SEMKO approvals match the project specifications. Confirm that the random phase characteristic aligns with the noise immunity needs of the application circuit.

Triac, SCR Output Optoisolators Selection Notes

Select this component when interfacing low-voltage electronic controls with higher voltage AC loads requiring random phase triggering. The 600 V rating supports 115 to 240 VAC operations. Consider the 1 kV/µs static dV/dt specification for environments with rapid voltage transients. The DIP package facilitates through-hole mounting for prototyping or industrial equipment.
